Even Massive Stars Fall Like a Feather

An artist created this picture to show a group of three stars bound together by gravity. The group includes two small white dwarf stars and a pulsar. The gravity on a pulsar is 2 billion times stronger than gravity on Earth, making it ideal for testing whether Einstein's theory of gravity still works when it comes to objects with super strong gravity. After studying these stars for 6 years, they've finally admitted that Einstein's theory has passed the test.
